SPECIFICATION forming part of Letters Patent No. 269,631, dated December 26, 1882.

n Application ilcdAugust23,1ES2. (Noniodel.)

To uit tti/tom it may concern Be it known that I, JOHN J. BRINKERHOFF, a citizen of the United States, residing at Auburn, in the countyof Cayuga and State of New York, have invented new and useful Improvements in Barbs for Fences, of which the following is a specitication.

My invention relates to sheet-metal barbs for fence-wires, and has for its object the provision of a blank which can be economically cut from a strip or sheet of metal in substan tial accordance with the method set forth in a patent heretofore granted J. and XV. M. Brinkerhoif, No. 258,014., datedv May 16, 1882, and which, when produced by that or any other method, will, by reason of the contour and relative location of the parts of the blank, be capable of ready and firm attachment to a strand or rail, and to this end my invention consists in certain features hereinafter described, and specitically'set forth in the claim.

Referring to the drawings, Figures 1, 4, 7, 10, and 13 are plans of barb-blanks constructed in accordance with my invention. Figs. 2, 5, 8, 11, and 14 are perspectives, respectively, of the above-mentioned blanks in the forni they assume when attached to a strand or rail 5 and Figs. 3, G, 9, 12, and 15 are perspectives, respectively, of said blanks and a portion of a rail comprising' two strands.

Like letters ret'er to like parts in all the tigures.

The requisites of a practicable barb-blank are economy in its production, readiness of application to the strand, and anatural tendency of the barbs of the blank to assume the to the strand.

proper direction and extent of projection by means of the force applied in setting the blank It will be noticed that each of the blanks shown comprises a body portion, A, and a series of barbs arranged to'project in opposite directions from said body portion and of different lengths, cach directly merged into the body portion and one or more of them separated from its or their companion barbs, or from a lip which performs a certain function of the barbs, as hereinafter described, the separation of the barbs leaving a space opposite the base of one of the series, in order that in their application they may pass by each other and assume the desired form. As i11ustrated, these features are applicable to barbl blanks having three ormore barbs and to barbs having barbs which merge into a`body portion at their barbless bases, and which, when applied, remain in a substantially unbent condition-a feature in itself not herein claimed, as it"is shown in another caseiiled simultaneously herewith.

vSpecifically the blank comprises the barbs B, C, I), and E, and a lip, a, formed by the outline of the blank and the slits 1 and 2 on either or both in accordance with the particular arrangement of the barbs to bring or locate the spaces cc as desired. rlhe function of the lip a is to complete the embracement of a strand by a barb without undue consumption ot' its length, so that when applied the barbs of a blank will project equal distances, and this function of embracement may be performed in the absence of a lip by increasing the length of a barb in the blank.

It', in a three-barbed blank, as Fig. 1, it is desired to locate the space w between the barb B and lip a, then slit 1 alone is made, while in other locations ot' the space or spaces slits 1 and 2 are both made, the latter completing the outline or formation of the lip and a portion of an adjacent barb.

In applying the blank to a strand it will be seen that in setting the body A to the strand, so as to conform to its circumference,the barbs and lips naturally take the desired positions or angles of projection by reason of the relan tive location of barbs and spaces and lip, and such location is susceptible of many variations, exceedingin number those shown, all embodying the gist of my invention. I therefore do not limit myself to any ofthe specific arrangements illustrated, but deem the features of construction which coact to render the blank readily applied and naturally assuming a desired distance and angle of projection in each barb as of my invention. When applied to a fencerail of two or more strands, as F G, one or more of the barbs may pass between the strands, if desired.

Haring thus described my inventiomwhat I claim isthe body portion A, provided with barbs B, C, and D, which extend in opposite directions, as described, and with a lip, a, opposite one of the barbs, said barbs and lip being separated j A barb-blank for fence-wire, consisting of roa nesses.
